在SP-2305E型色谱仪上设计了二维气相色谱流程,采用在线微型六通阀进行流路切换,用微型中间陷阱进行“再进样”。用自制石墨化碳黑毛细管柱和不同极性的填充预柱,对敌百虫副产氯甲烷中微量杂质进行了分离和定性。
The two-dimensional gas chromatograph was designed on the SP-2305E chromatograph. The on-line micro-six-way valve was used to switch the flow path and the micro-intermediate traps were used for “re-injection”. The trace impurities in chloroform by-product of trichlorfon were separated and characterized by self-made graphitized carbon black capillary column and packed column with different polarity.
